Hi Non-Twisty Puzzles fans,

Ring Bracelet is based on an idea by Carl Hoff. Carl's idea was to have a puzzle ring, in which the set of rings is linked in a loop, similar to Weave Five, such that the scrambled puzzle can be worn as a bracelet. He calculated that 10 rings would be needed for this. Bram Cohen analysed what the order of the rings should be in the solved state. I found a weave that worked and this is the first prototype.

The puzzle ring is quite different from other puzzle rings. Typically you drop a puzzle ring and it is scrambled. Not this one. When you drop it, all the rings stay together in the solved state. Rings are swivelled out one by one, and it is even a bit of a puzzle to figure our in which order they need to be moved. The puzzle is not too difficult to solve once you figure out the correct order of the rings.

The puzzle ring is not yet offered for sale, as this version feels a bit too flimsy and I am working on an improved version.

Watch the YouTube video.
Watch the puzzle at my Shapeways Shop.

I am also experiencing a problem with a model I setup for sale last night. The direct link I shared I Facebook seems to work but the model doesn't appear in my store. Very frustrating. Announced this product at a show and no one can find it in my shop. They can't search for it either.

I tried again today (Feb 7, 2016) and it seems to be working. I was able to get the model created and continue through the process and placed an order. I don't know if it was an issue or maybe just high traffic volume, but I am glad it is working. Thank you.

Model things that you have a personal interest in (and probably mechanical things rather than "organic" forms or figurines if you use SolidWorks). See what people are looking for help with in "3d modeler needed" and/or offer your services in "3d modelers for hire".
Upload a few of your existing designs, see if they conform to the material and printer limitations detailled under MAKE->Materials and if they would be affordable, eventually change their settings to "Display to the public" or even offer (printed copies of) them for sale so that people can see your portfolio.

Hi Jay,

you have quite a talent for understatement.

What I write below is not aimed at you specifically, it is a general lament...

I have been with SW for a while now, and the search has NEVER worked. The tags are also less than useful. Isn't it embarrassing that the only way to find stuff (still) is via a 3rd party search engine?

Instead of getting basic functionality working, things get 'fixed' that were never really broken. And effort that should go into getting the items that people actually want, like the search, like orientation, like group items and like variants (think ring sizes). Function that people like and use is removed/not maintained and arbitrary changes are made to the shops like messing up people's margins when the pricing model changes or cropping their photos without notification and badly.

SW should spend more time addressing what its users actually want and ask for, and less time in imagining what might be cool to do. A funky website was quite cool a few years back, but SW is no longer a start-up - get it together please.

This is just what they were doing again and again for years.

Nice tools to show our work like the pics that you can watch down right of the product page, and that are working right till a year ago, one nice day start to show randomly products in lieu of "related items", and the four pics that shows "more from -designer-" is impossible to configure at all. Designers warned about it, but never was fixed.

Some software engineers seem to work against logic, instead to watch the web under the eyes of a new customer or designer.

Another silver badge for the chest of somebody. Congrats.

Just for fun. Someone told me they wanted to know how to model the Rocketeer helmet, so I made a tutorial and though it would be great to get it printed.

Hello Shapeways,

I'm having problems with a specific design, or more specifically how it is being dealt with by Shapeways.
A few weeks ago I started selling a series of designs to the general public. So far, so good. One of those has a few areas that lay outside the guidelines, which I was aware of. No problem, they are guidelines, right? To make sure I tested them by ordering it myself first and after that through a friend. No issues were encountered, so I made it available to the public.

Now, after several orders I received a rejection on a customer's order. The reason given was that several items were too close to each other to assure they wouldn't merge together. A bit odd since the actual contact surface would probably be around 0,02 mm2 so is that really a problem? Also - I have seen strange orientations on printed items, so apparently your technicians are capable of moving shells around, but this was too complicated? Frankly it sounds like an excuse, especially since the order had already passed the original dead line. Can happen of course, but this was a FUD print which had enough time to be printed as the same order also included an FXD item.
The rejection email instructed me to upload a new file, so I repositioned these items and uploaded a new file so "This will ensure that you can continue to sell your product".
Not. Because of the new upload I apparently have lost the successful printing record of the old file and now it is being scrutinized all over again, rather than comparing it to the rejected design. So instead of getting happy customers, they get a second rejection! Details that were not considered an issue in the previous design now have become one. All of these are areas that have been printed successfully repeatedly and some are just nitpicking, considering the guidelines are just that: guidelines. I've been assured of that by your crew members on several occasions.

Please do something about the issue of redesigns being treated as if they are 100% new when the issue to be redesigned was specifically pointed out by Shapeways in the first place. Or at least change the text in your email, so it does not suggest it will be an easy fix.

More to the point, at what point will designs be safe from being rejected? How many times do they need to be printed before they keep being examined and run the risk of a technician finding an issue where his previous collegues did not? And for the record, the previous design was still at 83% when it was decided it would not be printed any more. So above the 80% threshold....

In many cases this would just be very annoying: a customer not getting what he ordered. In my case it is considerably worse: the design is part of a larger design, requiring more designs. One rejection means the rest of the items are useless. I've done my best to prevent this problem, both by ordering the designs myself first and by discussing it here on the forum and with Shapeways directly. What more can I do?
It's a bit cynical that if I help out my customers by ordering it as PIA I will get perfectly printed items and the more I do that the higher the success rate will be....

So far I've tried to discuss this issue through email, but since I've not received a reply after several days I'm trying to see if posting it here will have better luck. And yes, I do know it's weekend, but that hasn't stopped Shapeways from sending a rejection today either.

Hopefully the issue can be resolved ASAP. My first priority is getting my customers the items they ordered and need. It's making me look like an idiot and Shapeways as not being a serious company.

The goal is for the techs to NOT move the parts around. They do not know your intent/desires.

This is a known issue with the First-To-Try system. The difficulty is figuring out how to ascertain that some model had only "minor" changes. There are just too many possible variations on what might be considered "minor". I would suggest that some simplistic vertex comparison would be in order, but neither the humans nor the computers currently have a good method for detecting what is "the same". If you shift your model .001 to the left.. all the X/Y/Z coordinates change in the file. If you scale your model up or down by .01% ... all the X/Y/Z coordinates change. Simply removing a mesh with a lot of vertexes, could throw it over the threshold of whatever would be determined as a "minor" change. I know it was a minor change.. but the person (or computer) on the other end doesn't have a good way to detect that. Remember.. the humans see hundreds of models per day, they can't be expected to remember what they saw 15 minutes ago, much less 14+ days back to the last order.

Customer service.. service@shapeways.com is the way to go. It's not that Customer Service ignores the forum, but if you want a formal answer, it's going to have to get into their ticketing system.
I will say.. over the years, I've won some appeals, and I've lost some, requiring a re-design. There are (at least) two of my models that have to go unsold because the design criteria was changed so as to make them not viable. I lost the appeal on those two. But, upward and onward with the 262 other designs I have that DID sell last year.

All valid and well known points, but I still think that if Shapeways requests a change and suggests that's all you need to do they are not really telling the truth because it is not that easy. It would be if they check the new design against the old one and see the if things they wanted changed are. If they can't do that, they shouldn't suggest they do.

I wonder if it isn't possible to include an editor within Shapeways to carry out minor modifications, allowing Shapeways to keep track of the changes and keeping them from having to reexamine something as being a 'new design'. Would be a good idea for everybody I think.

If this was just one of many designs (I don't have hundreds like you, and this one is rather expensive too) I could ignore this, but I can't. Iit is part of a larger design that has been worked on over several years and the rejected design is absolutely crucial. The rest of an order is useless without it. Which is why I went to lengths to have it printed twice first. And now I've started a marketing campaign promoting the designs and the possibilities of 3D printing (and Shapeways in the process) the entire project is put on hold. Quite frustrating.

And yes, I know moving things around is not Shapeways intention, but they do. It takes time and I think it is bad for everybody. They've screwed up quite a few prints like that in the past (all dealt with very, very well by Customer Service though!). As an example, I had over 200 interlocking parts delivered in a bag as individual pieces. Impossible without moving the shells around, and actually requiring more machine space. My point was that the technicians are able to do something like that, but moving three parts 0,04mm is a problem.
To be fair, it seems they used to move stuff around much more often than they do now and I applaud this change very much (even if it is only a perceived change)! It seems to have significantly reduced the number of missprints.

Shapeways is generally doing a very good job, but there should be a better link between old-new designs and order histories. It is also annoying designers do not get 24-48 hours to fix a problem in a design ordered by a customer. Would that really be that difficult? Especially if there is an editing environment. All that was needed in this case would have been moving three parts 0,04 mm and this whole mess would have been avoided.

To finish, all this is still being investigated by the Customer Service. Hopefully they'll come with a solution soon and I'm always willing to discuss the option in person when I come to pick up another order in a few days.

I do believe that all of the examples I've included are indeed polished bronze steel. Shapeways doesn't offer any other bronze finishes besides 'raw' and a highly polished real bronze. No gold finish would be as dark.

Another exciting round of comparison, to show what, apparently, is Shapeways acceptable quality control range for polishing:

My point was that the tumbler polishing is a somewhat random process with inherently variable results, and as nobody is required to add actual product photos to their shop items it seems likely that most such photos will show near perfect parts that the designer was proud to showcase.
Have you sent these detail images to service as well ? From your initial description it sounds as if shapeways contacted ExOne (or whoever did the printing) with just "the customer says his part was not polished at all" and received a reply like "but our records show that it was tumbled".

I'm not really on anyone's side here. I'll give Shapeways the benefit of the doubt and assume that the printing process itself has high variability over time. In other words some prints come out of the infusion process with minor print steps and others come out with big stepping. So the issue may not be the "polishing" step because what would really be needed in some cases is "grinding" which is a more severe process to get to a very smooth surface. But that risks losing details on some models that people would also complain about so to some extent they are walking a tightrope here to make everyone joyously happy with their prints. But obviously things have been worded to allow prints to have some variability. I don't know what the solutions are here other than to hope for improvements at one or more points in the overall print/infusion process. Maybe they can add a process option to grind the heck out of pieces for an extra fee.

These aren't shop listing photos, it sounded like most of the images I referenced were the first prints these users received, in the "It Arrived!" section of the forum. Not the 'best of the best' from a large group over time. I think that if somebody ordered a polished model and gets one that looks identical to a raw model, and customer service refuses to admit an error, the designer wouldn't just suck it up and keep trying until they get one that looks like it's been through a polishing process. Service has seen plenty of evidence of the difference between the two models, and I can always send them a link to this thread, or the one on the RPF, or facebook, if they need further clarification.

I hear ya mrnibbles, but I must assume the build layer height hasn't changed over time, and that would be the only printing variable that would change the intensity of the stepping outside of a polish process. The problem is, knowing this is what they call polished, why the heck would anybody order it, as it looks exactly the same as a raw model? Maybe the extra process option they would charge for is to have somebody actually look at the models before they go out and determine whether they look like they've been polished, and if not, to put it (back?) in the tumbler until it comes out with some shine. Some places that's called quality control, and comes standard with your order.

My first skull with the nickel finish clearly went through a tumbler, and wasn't ground by hand. If I give you a rare rib roast and you complain, then i refuse to fix it because it verifiably spent 3 hours in an oven, whether or not the oven was warm, how likely are you to return to my establishment? All that needs to be done by Shapeways is to be sure that all 'polished' models go out with a similar level of wear, not by the number of minutes and seconds spent riding on top of media in a closed drum.

Hello

I'm using the Shapeways' Python module to connect to the API, but am running into trouble getting an access token from Shapeways. I'm using Flask to develop my web application. Here's the relevant extract of what I've got so far:

from shapeways.client import Client

consumer_key = foo
consumer_secret = bar
callback_url = "http://127.0.0.1:5000/callback"

@app.route("/shapeways") # When user visits this URL they are redirected to Shapeways to login
def shapeways():
    client = Client(consumer_key, consumer_secret, callback_url)
    url = client.connect()
    return redirect(url, code=302)

@app.route("/callback") # This is the callback URL
def callback():
    oauth_token = request.args.get("oauth_token", 0, type=str)
    oauth_verifier = request.args.get("oauth_verifier", 0, type=str)
    client = Client(consumer_key, consumer_secret)
    client.verify(oauth_token, oauth_verifier) # Shapeways returns signature_invalid
    #client.verify_url(str(request)) # Shapeways returns verifier_invalid


The problem I run into is that Shapeways returns an OAuth error – saying either the signature or the verifier are invalid (depending on which approach I use for sending the oauth_token and oauth_verifier – see last two lines).

After reading this post, I wonder if it's because I'm not including a 'oauth_token_secret' parameter, but I can't see any reference to this in the API docs (and I don't receive this parameter in the callback).

Can anyone provide a pointer?

I just installed the Shapeways API for Python using "pip install shapeways" and then building the docs. When I try to run the application, after updating the example with my user id and password, I get the following error:

{"reason": "Authentication Error", "result": "failure", "oauth_error_message": " oauth_problem=parameter_absent&oauth_parameters_absent=o auth_token "}

What gives?

Message is asking for an oauth_token so I gave it one. The example clearly did not have one but hey. So I add the oauth_token and oauth_secret using my Shapeways account name and password (not being sure what else to use). Now the error message is:

{"reason": "Authentication Error", "result": "failure", "oauth_error_message": "oauth_problem=token_rejected"}

Thanks in advance,
Will

Which library are you using? If you are using the code that I uploaded, I'm not sure that I got everything in there to allow pip to install it "right".

Your token(s) need to be generated. They will look something like this:
client_key=u'9aad5bd0e989dbd7a785f14ab9ab822935fb007c'
client_secret=u'70cfc456a15beaf4b9a7be9be22e79c11008342f'
resource_owner_token=u'06af2b8daaeb98a4e4e45bab4dad004e7f621 4c7'
resource_owner_secret=u'4b30000ac21911ab9cbd865402f32fd638e4 13d7'

Did you follow the steps in the file "Directions.txt"?

Thanks thanks thanks. Not working yet but at least I have a directions.txt with a step that gets me Oauth keys! Not sure why I had not found that post as that is what I was searching for!

Unfortunately ... I am back as I am still getting an authorization error. I ran GetKeys and it completed nicely after updating the lower part of the keys file. However, when I run the program to list models it failed (with the print statement uncommented):

u'reason': u'Authentication Error', u'result': u'failure', u'oauth_error_message': u'oauth_problem=signature_invalid&debug_sbs=GET&http%3A%2F%2Fapi.shapeways.com%2Fmodel%2Fv1&oauth_consumer_key%xxxx%26oauth_nonce%xxxx%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1454880344%26oauth_token%xxxx%26oauth_version%3D1.0%26page%3D1'}

I can see something like this working well. I recently ordered some models that the designer had made available in WSF Polished only.

WSF Polished came out very well in most of the design, but a few small details were utterly destroyed by the polishing process.

It would be nice to be able to, for example, offer the main model in WSF Polished as the designer intended, but have the small detail pieces in FUD. It would require a little assembly work from the buyer, but that would be much better than receiving a model that doesn't live up to snuff.

I have several models that I ordered a few years ago in WSF. They came out quite nicely, the surface had a slight grainy texture to it but this was quite acceptable and it took paint very well. Surface details were crisp and clear.

I just recently received some new models in WSF and they are of much lower quality. The surface is not so much "grainy" as it is "pitted", as if the model were made of pumice instead of a solid plastic. Surface details were worn and barely visible. This is really deeply disappointing.

Could be a printer in need of recalibration, a problem with a batch of raw nylon powder or a case of inadequate model orientation in the print volume. Best email your complaint (ideally accompanied by a few pictures of the offending models) to service@shapeways.com so that they can check what happened and hopefully get you a reprint.

I've had these same angled print lines (if that's what they are) on some recent FUD models I received in mid December 2015. They are very distracting to say the least. I have had the same models printed before without these lines, so I know it can be avoided. It takes some serious effort to get rid of these lines while preserving the delicate printed detail elsewhere.

I would like some guidance from Shapeways on what, if anything, we as designers can do to influence the best finish on our models. Some surfaces of my models I just don't care about because they are hidden. Other surfaces must be executed as accurately as possible or the model is a failure. This has come up in the print orientation discussion but I think it needs to get beyond the scope of that discussion. I shouldn't need to be an expert in 3D printing orientation (and I'm not) in order to specify the surfaces I want to appear the best. It's an insult to the trained professionals for me to tell them how to do their job. Instead, I should be able to specify where I want the best quality surface and leave it to the professionals to deliver on this specification.

The hit and miss nature of this process isn't just tiresome, it's also expensive. I can't effectively make a good argument for people to buy my models if the results they are going to get are so inconsistent. I certainly won't get repeat customers if the model is a failure. I am going to buy a certain amount of my own designs for myself. I can choose any 3D printing provider for that purpose and quality is the primary driver in that choice. Shapeways offers a marketplace to share our designs and to sell them without setting up our own marketplace, keeping inventory, etc. If the quality isn't wrestled under control soon, the benefits of the marketplace will cease to exist. Instead, I will be forced to forge a new reputation with another vendor.

It's as if somebody (possibly another shop, if SW outsourced these wacky prints, or a new SW employee trained by some other shop) has only one concern- that of minimizing support material, to the point of totally disregarding print quality and customer satisfaction.

I'm still cursing as I clean up a $100 model that was printed like that.

Please, SW, enable print orientation (for those who know enough to care) and be done with this crap!
